6.7基于命令行方式使用 Kafka

1、 创建主题

$ kafka-topics.sh --create \

--topic itcasttopic \

--partitions 3 \

--replication-factor 2 \

--zookeeper hadoop01:2181,hadoop02:2181,hadoop03:2181

2、向主题中发送消息数据

$ kafka-console-producer.sh \

--broker-list hadoop01:9092,hadoop02:9092,hadoop03:9092 \

--topic itcasttopic

--hello kafka

3、消费主题中的消息

$ kafka-console-consumer.sh \

--from-beginning --topic itcasttopic \

--bootstrap-server hadoop01:9092,hadoop02:9092,hadoop03:9092
